Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine. Oxidative stress and inflammation play a major role in IBS. Considering the antioxidant properties of ellagic acid (EA), this study was designed to evaluate the effect of EA on oxidative stress index, inflammatory markers, and quality of life in patients with IBS. This research was conducted as a randomized, double-blind, placebo-controlled clinical trial; 44 patients with IBS were recruited. Patients who met the inclusion criteria were randomly allocated to consume a capsule containing 180 mg of EA per day (n = 22) or a placebo (n = 22) for 8 weeks. Serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), and interleukin-6 (IL-6) were measured at the beginning and the end of the study. Also, quality of life was assessed using a self-report questionnaire for IBS patients (IBS-QOL). At the end of the study, we saw a significant decrease and increase in the MDA and TAC in the intervention group, respectively (p < 0.05). Also, EA consumption reduced CRP and IL-6 levels, and these changes were significant in comparison with placebo group changes (p < 0.05). The overall score of IBS-QOL significantly decreased, and quality of life was increased (p < 0.05), but there were no significant changes in the placebo group. According to these findings, receiving polyphenols, such as EA, may help maintain intestinal health by modulating inflammation and oxidative stress and ultimately improving the quality of life in IBS patients.

An insufficient intake of magnesium may be associated with the development of chronic obstructive pulmonary disease (COPD). We aimed to determine the relationship between health related quality of life (QoL), anthropometric indices and nutritional status with dietary magnesium intake in COPD patients. Sixty-one COPD patients participated in this cross-sectional study. QoL and nutritional status were assessed. Furthermore, body composition, calf circumference, and muscle strength were measured; equations were used to calculate fat-free mass index, body mass index, and muscle mass value. Dietary magnesium intake was assessed by three 24-hours recalls and magnesium intake was categorized as ≤ 188.08 mg/day (A group) and > 188.08 mg/day (B group). The χ2, independent-sample t-test and Mann-Whitney test were used for statistical analysis. The p values less than 0.05 were considered significant. Of QoL assessments the total and impact mean scores of St. George's respiratory questionnaire in the B group were significantly lower than the means of the A group (p value = 0.007 and 0.005, respectively). The instrumental activity of daily living score was significantly improved in patients with higher consumption of dietary magnesium (p = 0.02). Participants had a significantly lower mean score of patient-generated subjective global assessment in the B group compared to the A group (p = 0.003). Higher intake of dietary magnesium can lead to improve QoL and nutrition status.

Menopausal symptoms can persist or worsen even years after menopause and affect women's quality of life. We investigated whether menopausal symptoms were alleviated through a marine healing program and if sea mustard intake additionally benefits these symptoms. A total of 42 menopausal women self-selected to participate as the marine (n = 22) or city group (n = 20). The marine group participated in a 5-day marine healing program consisting of a balanced diet, exercise, and mind-body practices using ocean resources. The city group continued one's daily routine without any intervention. Within the marine group, participants were randomly assigned to consume sea mustard (

Plasma homocysteine level and megaloblastic anemia status are two factors that can affect the quality of life of patients with multiple sclerosis (MS). We conducted this study to determine the effect of vitamin B12 and folic acid supplementation on serum homocysteine, megaloblastic anemia status and quality of life of patients with MS. A total of 50 patients with relapsing remitting multiple sclerosis (RRMS) included in this study which divided into 2 groups. The vitamin group received 5 mg folic acid tablet daily and 3 doses of vitamin B12 (1,000 mcg) injection and the other group received placebo and normal saline injection (same doses). The quality of life was measured by using Multiple Sclerosis Quality of Life-54 questionnaire (MSQOL-54). Fully automated fluorescence polarization immunoassay was used to measure serum homocysteine, vitamin B12 and folate. Complete blood count blood test was conducted to determine the anemia status. The mean homocysteine level reduced by 2.49 ± 0.39 µmol/L (p = 0.001), hemoglobin increased from 11.24 ± 1.54 to 13.12 ± 1.05 g/dL (p = 0.001), and mean corpuscular volume decreased from 95.50 ± 6.65 to 89.64 ± 4.24 in the vitamin group (p = 0.001). There was a significant improvement in the mental field of life quality in the placebo group (37.46 ± 19.01 to 50.98 ± 21.64; p = 0.001), whereas both physical and mental fields of quality of life were improved significantly in the vitamin group (40.38 ± 15.07 to 59.21 ± 12.32 and 29.58 ± 15.99 to 51.68 ± 18.22, respectively; p = 0.001). Serum homocysteine level decrease and anemia status improvement with vitamin B12 and folic acid supplementation reveal the potential role of these two vitamins in improving the life quality of MS patients.

The aim of this study was to compare the quality of life (QoL) depending on the postoperative survival period or nutritional status in gastric cancer patients. Surviving gastric cancer patients (n = 222) after the gastrectomy were included in the study at Soonchunhyang University Bucheon Hospital from April 2010 to August 2012. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and a gastric cancer-specific module, the EORTC QLQ-STO22, were used to assess the QoL. The postoperative survival period of the patients fell into two groups; the less-than-1-year group or the more-than-1-year group, and the nutritional status of the patients fell into three groups by a score of patient generated-subjective global assessment (SGA)-A, B, and C. As a result, the rate of malnutrition was 34.5% in the less-than-1-year group and 19.8% in the more-than-1-year group, respectively. Score for the fatigue (p = 0.006), loss of appetite (p = 0.002), reflux (p = 0.027) and body image (p = 0.004) in which the QoL was significantly lower in the less-than-1-year group than in the more-than-1-year group. The score of QoL according to the nutritional status of all subjects, overall health status (p = 0.043), physical functioning (p = 0.016), fatigue (p = 0.006), pain (p = 0.028), loss of appetite (p = 0.017), reflux (p = 0.003), eating restriction (p = 0.002), anxiety (p = 0.010), and body image (p = 0.001) was significantly lower in the SGA-C group than in other SGA groups. These results suggest that the nutritional status of the gastrectomy patients with stomach cancer may impact on their QoL. It is necessary to to develop nutritional intervention to improve QoL in gastric cancer patients with postoperative malnutrition.

It is generally accepted that diet modification provides beneficial effects on the management of diabetes. In the present study, we evaluated the effects of diet modification on nutrient intake and quality of life in a large sample of diabetic patients. This study was conducted using data from the Korea National Health and Nutrition Examination Survey IV and V (2007-2010). A total of 2,484 of diabetic patients were included in the analysis. Then, we compared the overall quality of dietary intake between diabetic patients with diet modification and those without dietary modification. The result showed that subjects on diabetic diet (DDG) showed lower levels of total cholesterol, triglyceride, and AST before and after the adjustment for covariates (all p < 0.05). The results of nutrient assessment showed that DDG had lower intakes of total energy, fat, and carbohydrate (all p < 0.05), but higher intakes of energy from protein, vitamin B1, vitamin B2, niacin and vitamin C than NDG. (all p < 0.05). In addition, nutritional adequacy ratio of calcium and vitamin B2 were significantly higher in DDG than those in normal diet group (NDG) (p < 0.05). However, we observed no significant differences in quality of life between two groups. In conclusion, diet modification in diabetic patients seemed to be effective to improve blood lipid profile and the adequacy of nutrient intake without sacrificing the quality of life.
